Align OSM file to the terrain in Houdini

Hello, I am trying to design a terrain for UE4 that includes OSM data imported from OpenStreetMaps. My question is how do I align the OSM file to the terrain created in houdini? When importing the OSM file it put the data on a flat plane, and I cannot figure out how to align it to my imported heightmap. Any help would be appreciated. Thank you.
